ANTl-RATTLER FOR THlLL-COUPLINGS.

SPECIFICATION forming part of Letters Patent 1%. 443,251, dated December23, 1890.

Application filed October 23, 18901 Serial No, 869,119 (No model.)

To all whom it may concern.-

Be it known that I, CLARENCE A. CARMAN, of Paterson, in the county ofPassaic and State New Jersey, have invented a new and ImprovedAnti-Rattler, of which the following is a full, clear, and exactdescription.

My present invention relates to anti-rat tling attachments forthill-couplings, the obj ect of the invention being to improve upon theconstruction illustrated and described in my prior patent, No. 431,507,which said patent was issued to me on the 1st day of July, A. D. 1890,the present invention consisting of a frame, a spring-wire coiledthereon and formed with upwardly-extending arms, and a means foradjusting said arms, all as will be hereinafter more fully described,and specifically pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar reference figures and lettersindicate corresponding parts in all the views.

Figure 1 is a side view of my improved antirattler, the same beingrepresented as it appears when in a position for use in connection witha thill-coupling. Fig. 2 is a face view of the anti-rattling attachment,the thill-coupling being shown in section. Fig. 3 is an inverted planview, and Fig. 4 is a sectional view on line 4 4 of Fig. 2.

In the drawings, 10 represents an axle-clip, and 11 a thill-iron ofordinary form.

12 is a frame consisting, preferably, of a plate 2, having depending andforwardly-extending arms 3, that are connected by acrossbar or pin 4. Inpractice I prefer to make the frame 10, with the exception of thecrossbar 4, of malleable iron; but it will of course be understood thatthe frame could be made of any other proper material. The cross-bar 4would usually be made from wire, and said wire being cut in lengths, andthese lengths passed through apertures formed in the arms 3 and retainedin position by riveting the ends of the wire, as will be readilyunderstood.

The frame above described is substantially the same as the oneillustrated in my former application; but instead of using, as in theapplication just referred to, a spring supporting-block, I form thespring from a single length of wire that is coiled upon the cross-bar 4at the points a a, between which points the body of the wire extends tothe rear in the form of a loop I), the ends of the wire being carriedbackward and upward to form spring=arms c c.

In order that the arms 0 0' may be thrown forward or backward and theirpressure upon the thill-iron thus increased or diminished, I provide anadjuster 13, which engages the loop I), and passes upward through anaperture formed in the plate 2, there to be engaged by a nut 14, theupper end of the adjuster being threaded, as represented in thedrawings. Although the adjuster could be made in any proper way, Igreatly prefer to make it from malleable iron, making the lower end inthe form of an open hook, as 6, which hook may be readily brought intoengagement with the projection b, and then the end of the hook may beforced down to the position in which thus be thrown forward and will actwith greater effect upon the thill-iron.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. In an anti-rattling attachment, the combination, with a frame, of aspring-wire coiled thereon and formed with upwardly-extending arms thatare arranged to bear against the thill-iron eyes, and a means foradjusting the arms, substantially as described.

2. In an anti-rattling attachment, the combination, with a frame, of aspring-wire coiled thereon and formed with a rearwardly-extendingprojection and with upwardly-extending arms that are arranged to bearagainst the thill-iron eyes, and an adjuster connectedroarwardly-extendingproj ection of the spring- 10 wire, and with anupwardly-extend111g stein that passes through the upper portion of theframe, substantially as described.
